AUTOMATIC CULTIVATOR-TOOTH-RELEASING MEANS.

Application filed May 20,

To (ZZZ whom it may concern:

Be it known that I, GEORGE. M. RAMAGE, a citizen of the United States, residing at Snyder, in the county of Scurry and State of Texas, have invented certain new and useful Improvements in Automatic Cultivator-Tooth-Releasing Means, of which the following is a specification.

This invention relates to new and useful improvements in planter attachments and has for its principal object to provide a means for automatically releasing the cultivator toot-h when the same encounters an obstruction, thereby preventing the break ing of the tooth and automatically returning the same to its normal position after the planter has passed over the obstruction.

A further object of the invention is to provide a planter attachment of the above mentioned character, wherein the cultivator beam is adjustably supported on the foot of the planter, so as to regulate the depth at which the tooth is to operate.

A further object is to provide a device of the above mentioned character, which is simple in construction, inexpensive, strong and durable, and furthermore adapted for the purposes for which it is designated.

Other objects and advantages of this in vention will become apparent during the course of the following description.

In the accompanying drawing, forming part of this specification, and in which like numerals designate like parts throughout the same:

Figure 1 is a side elevation of the ele ments embodying the invention, and

Figure 2 is a top plan view thereof.

In the drawing, wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates the foot of a planter and secured thereto onopposite sides thereof are the brackets 2 and 3 respectively. The brackets extend rearwardly from the foot 1 and the rearwardly extending portions are provided with registering apertures such as are shown: at a in the drawing. The rearwardly extending portions of the brackets are furthermore provided with registering elongated slots such as shown at 5, and the purpose of this construction will be presently described.

Disposed between the brackets 2 and 3 is the inner end of the plow or cultivator beam 6. The inner end of the beam is pivotally 1924. Serial No. 714,622.

supported at 7 and the pivot is adapted to extend through one pair of registering openings 4L provided in the rearwardly extending portion of the brackets.

Extending through the registering slots provided in the bracket is the bolt 8 and a suitable washer 9 is carried thereon and adapted to engage the corrugations 10 provided on the outer face of the rearwardly extending portion of the bracket 3, it being understood that the inner face of the washer is also corrugated, to cooperate with the corrugations 10. A nut 11 is threaded on the bolt 8 and the bolt is disposed below the under side of the beam for supporting the same in the proper adjusted positions with respect to the brackets in the manner as is obvious from the construction shown in Figure 1.

Pivotally supported at 12 on the lower end of the beam 6 is the cultivator tooth carrying shank 13. The shank is provided on its upper end with the extension 14 which fits around the lower end of the beam and is adapted to engage the stop member 15 carried by the lower end of the beam. The cultivator tooth 16 is fastened to the shank 13 by any suitable fastening means, such as shown at 17.

For normally holding the tooth 16 in an operative position when the planter is in use, I provide the coil spring 18, one end of which is connected to the foot 1 in the manner shown at 19, while the opposite end is fastened to the eye portion 20 of a bolt 21 which extends through the shank 13 and receives on its threaded end the adjusting nut 14 whereby the tension of the spring may be regulated as is desired.

Normally, the parts are arranged as shown in Figure 1 of the drawings, and as the planter moves along the ground, the tooth 16 will work in the soil for the pun poses for which it is designated. Should the tooth accidentally encounter a stump or any other obstruction, the tooth will automatically swing on its pivot 12 against the tension of the coil spring 18 whereby the planter on its forward movement will be caused to move the tooth over the obstruction in such a manner as to prevent the breaking off of the tooth and after the tooth has passed the obstruction, the coil spring 18 will return the same to its normal position. The extension 14 will then engage the stop 15 and limit the forward swinging movement of the tooth and the shank upon which the same 'is mounted.

It will thus be seen from the foregoing description, that an automatic release for acultivator tooth has been'provided"which is simple in construction, strong and durable and further will positively enable the tooth to be returned to its normal operative posi-- tion after the same has passed the obstruction which 1t has encountered. In this manner consrderable expense will be sa ve d by 'ob-viating the'necessityof having to 'purchase new plow teeth-and thenut- :14 en I ables the tension of thecoil spring 18 to be regulatedso-as to assure-the proper opera- "tion thereof in returning the cultivator tooth 'to itsnormal operative position.

While I have" shown the: preferredvem- -bediment of my invention, it is'to be' under- 20 and arrangement of 1 parts may-be resorted to, without "departing-from thef'spiritof stood 'th'atvari'ous changes in :the "size; shape the in vention and the scopeof the ap pend- Having thus I described my "invention,

" what I- claim is "1.--In combination, a plow font, at bracket secured thereto and extending rearwardly itherefremy said bracket "including spaced i'p'lates arranged on {opposite sides of the foot, means for pivotally and adjustably curing" the inner end of a plow beam between said plates of said bracket, a plow t-ooth pivotally supported on the lower end of the beam," a coil spring secured at one end to the plow foot and to the tooth at its opposite end, means for regulating the tension ofsaidzspring, and means for limiting the movement of the tooth in one direction.

.2.- In combination, a plow foot, a bracket seeured thereto and extending rearwardly therefrom, said bracket including spaced plates-arranged on opposite sides of the foot, means for pimtally-andadjustably v securing the inner end-of a plow beam between said plates iof maid bracket,-an(la ing members and adapted for engagement with a stop'prox'id'ed on the lower end of the 'beam.
